My T-3 7mm-08 did not need any break in. Once I got it on paper, I cleaned it. Then I got it zeroed at 100 yds. Was using 140 grain Remington Premier nosler ballistic tips to zero rifle, then as an experiment I switched to the Hornady LM 139 grain sst. Believe it or not they shot the same hole as the ballistic tips. I have not cleaned it since. Been carrying it to the woods every chance I get, but have not seen a buck that I would like to shoot. I do not want to give my stand away quite yet, but I am sure that I will take a deer with my new Tikka7-mm08.
Shot it about 20 times since the last cleaning, and it still holds a perfect zero. I am not going to clean the barrel until after hunting season. Just going to keep it wiped down.
I am glad the T-3 likes the 139 grain Hornady SST, because it is a awsome round on a deer. You hit one where you need to, it will split muscle tissue in the @$$ and punch a hole you can take a picture through. Killed a couple with my .270 last year, wow, talk about a quick Kill.
I guess what I am trying to say is, just shoot it you'll like it!!!! :lol:
